Android : Android,Sms,BroadcastReceiver

I want to update total messages i.e. count and date of last sms and last sms when new sms received. But its not happening, its happened only when I relaunch activity.

     getAll.clear();
        Uri SMS_INBOX = Uri.parse("content://mms-sms/conversations?simple=true");

         c = getContentResolver().query(SMS_INBOX, null, null, null, "date DESC");

            startManagingCursor(c);
            count = new String[c.getCount()];
            snippet = new String[c.getCount()];
          thread_id = new String[c.getCount()];

            String[] num=new String[c.getCount()];
         date=new String[c.getCount()];
         address=new String[c.getCount()];
          c.moveToFirst();
            for (int i = 0; i < c.getCount(); i++) 
            {
                count[i] = c.getString(c.getColumnIndexOrThrow("message_count"))
                        .toString();
                thread_id[i] = c.getString(c.getColumnIndexOrThrow("_id"))
                        .toString();
                snippet[i] = c.getString(c.getColumnIndexOrThrow("snippet"))
                        .toString();
                date[i]=c.getString(c.getColumnIndexOrThrow("date"))
                        .toString();

                cur=getContentResolver().query(Uri.parse("content://sms/"), null, "thread_id = " + thread_id[i], null, null);
                startManagingCursor(cur);
                cur.moveToFirst();
                     num[i]=getContactName(this,cur.getString(cur.getColumnIndexOrThrow("address")).toString());
               address[i]=cur.getString(cur.getColumnIndexOrThrow("address")).toString();
               getAll.add(count[i]+","+num[i]+","+snippet[i]);
               cur.moveToNext();

              c.moveToNext();

            }
            adapter = new HomeAdapter(this, R.layout.sms, getAll,date);

            adapter.notifyDataSetChanged();
            list.setAdapter(adapter);

        if (null != bndl)
              {
     //---retrieve the SMS message received---
                  Object[] pdus = (Object[]) bndl.get("pdus");

                  msg = new SmsMessage[pdus.length];  

                  for (int i=0; i<msg.length; i++){
                      msg[i] = SmsMessage.createFromPdu((byte[])pdus[i]);            
                      contentTitle=msg[i].getOriginatingAddress().toString();
                      //contentTitle = (String) DateFormat.format("dd/MM/yy:hh:mm a", new Date(msg[i].getTimestampMillis()));
                      contentText = msg[i].getMessageBody().toString();

                        }
                  }

I tried all methods but failed to update and don't know what to do now. I been stuck on this problem from 6 hours.
